Notification pop-ups are interruption tests 🔔
If they appear at the wrong moment, users dismiss them. If they’re clear and well-timed, they create value.
What matters most here: → timing → clear value proposition → easy opt-out
What makes you say yes to notifications?

📦 The App Store release is part of development — not the last checkbox.
A lot of teams finish the feature work first and only then think about release.
That creates unnecessary surprises:
• missing permissions
• broken Sign in with Apple flow
• privacy declarations
• subscription metadata
• screenshots and review notes
• versioning issues
• environment configuration
• production API mistakes
• crash reports after release
For React Native projects, I prefer preparing the release flow early.
By the time the app is “finished,” TestFlight, production builds, store configuration, and release checks should already be familiar.
Shipping should be boring. That’s usually a sign the process is working. 🚀
i once worked with a founder who was about to start testing his product with 4–5 real industry users.
they were super early and b2b btw.
then his internal team started talking about analytics
→ what should we track?
→ what KPIs matter?
→ what should go into posthog?
i had to weigh in, “it’s too early for that” i said.
told them that at this stage (honestly at any stage) we had to do only 2 things…
1. watch what they do
→ where they stopped
→ what confused them
→ what they completely ignored
2. talk to them
→ we’ll understand the problem we’re solving better
→ we build rapport and trust. they tell us what’s actually bothering them
that’s it.
you don’t need more data, especially when you’re this early.
Plumbline Property Advisory, Budapest
Plumbline turns “can you check this flat before I sign on Friday?” into a booked, access-checked visit in two minutes, so a solo building engineer in Budapest stops losing buyers while she's up in an attic.
The business (fictional, modelled on a real Budapest practice): Réka checks flats and houses before people buy them (55,000 HUF for a flat, 75,000 HUF for a house, travel fee outside the city). Her quirks: every buyer has a hard deadline, the day they sign the deposit; 1 visit in 6 fails because nobody opens the door; and messages arrive at midnight in German, English and Hungarian while she's on site.
What I built:
→ Deadline-aware booking: only times before the deposit date, travel zone and fee from the district, route-friendly slots
→ Private links for the buyer and the listing agent: the agent confirms access with one tap. If they don't, the buyer and Réka are warned 24 h ahead, not on the doorstep
→ AI inbox: paste a WhatsApp in any language and get the address, deadline and language extracted, 3 free times and a drafted reply. Times and prices come from tested code, never from the AI
→ The buyer's own note becomes an AI site brief for Réka
→ Owner view: today's route, the one thing that needs her, time saved this week
→ English · German · Hungarian everywhere, real email notifications, and a demo clock ("time travel") to watch reminders and alerts happen
Before → after: ~2 days → ~2 min to confirm · ~25 min → ~0 admin per booking · locked doors caught a day early
